Abstract:
T his paper proposes a f ragile watermarking method for image authent icat ion. In the method, the orig inal image’ s feature is ext racted using the w avelet t ransform and encrypted by the Hash funct ion, so the w atermark sequences are generated f rom the message digest. It realizes a nonlinear multiple bits embedding method based on a shif t ing window . This paper develops a secure detection algorithm w ithout original image, the high probability detect ion ability is ensured. Experiment s show the method is very useful for image authent icat ion.
